Since Mariko joined Dentsu in 2012, she has always felt the power of words as she worked on building brand concepts, developing new products, special design, as well as traditional advertising for various clients. ‘WE'RE HIRING...BASED ON LOOKS!’---the seemingly controversial copy was actually a strong message for the cosmetic brand Isehan to promote the freedom of expression through make-up. While dealing with serious social issues, Mariko finds a way to keep things light-hearted and relevant to her generation. She has worked for clients such as Japan Railway, The ad museum Tokyo, and Mitsubishi Estate, and has won international accolade at Cannes, ONE SHOW, Spikes, and just recently won a Grand Prix at Cannes Lions.
